Language practice
I visited the Giant’s Causeway two years ago.
It produces electricity for millions of people.
I’ve never seen it, so I’m not sure I agree with you.
I looked into the east — the sky was becoming grey.
You’ll get there in five minutes.
Am I going the right way?

重要回顧
1. I think natural wonders are more interesting than man-made ones.
1) I think 為主句，后面是省略了連接詞that的賓語(yǔ)從句。
2) ones 作代詞，指代wonders。 ones 指代復(fù)數(shù)名詞，同類不同物。
2.Far below me，the ground fall away and down to a river.
在我下方很遠(yuǎn)，地面沉降到下面深谷中的一條河里。
fall away 消失/疏遠(yuǎn)
